LIGHTING DEVICE FOR KEY RINGS Filed Nov. 26, 1928 2 Shets-Sheet 2 yllllllllllllllllllllllfi small Patented July 28, 1931 UNITED STATES PATENT OFFICE ABRAM LOUIS JEANNERET, OF LA CHAUX-DE-FONDS, SWITZERLAND, ASSIGNOR TO COMPTOIR GENERAL DE VENTE DE LA MONTH-E ROSKOPF SOCIETE ANONYME VVE. OHS. LEON SCHMID & 0113., OF LA CHAUX-DE-FONDS, SWITZERLAND LIGHTING DEVICE FOR KEY RINGS Application filed November 26, 1928, Serial No. 321,984, and in Switzerland April 25, 1928.

The present invention relates to a lighting device such as a luminous watch in combination with a key ring. Itis the object of the present invention to combine in one single body the advantages of a luminous watch and of a ring available for holding a bunch of keys. The device is intended for lighting the key hole in the dark when the key has to be introduced. 7

10 The invention consists in that the watch is arranged in the middle of the ring of a key bunch said ring made in two parts being hinged to the watch-case and being kept closed by a device likewise provided on said watchcase. i

The annexed drawings represent as an example three working forms of the object of the invention.

The Figure 1 is a front view partly in section showing with mixed lines the open pos tion of the arms of the ring.

The Figure 2 represents at an enlarged scale a section of the pendant of the watch.

The Figure 3 shows the manner of working of one form of the invention.

The Figure 4 is a front elevation of a second working form.

The Figure 5 is a side elevation of the same showing the locking device in section and the ring closed. I

The Figure 6 shows the same piece with the opened ring.

The Figure 7 is an enlarged sectional view according to line VIIVII ofthe Figure 4,

a5 and The Figure 8 is a third working form.

According to the Figures 1 to 3 the watchcase a is provided diametrically opposite to the pendant with a lug b to which are hinged 40 two arms 0, forming two halves of the key ring. A leaf spring (7 tends to maintain the arms in their open position. There are notches 6 made at the free ends of said arms and hooks f, hinged at g on a flanged part of 4.5 the pendant h of the watch.

These two hooks are swingingly arranged within the same plane parallel to the dial. Their tail ends 2' (Fig. 2) are pressed upon by a helical spring k for the purpose of keep ing the hook ends f always engaged in the notches e of the arms 0. A Washer] on the stem of the watch rests on the tail ends i of the hooks and is in reach of the pins m of the pusher knob n mounted in the pendant. I \Vh'en pressing on the knob n in the closed position of the ring the hooks f will be withdrawn from the notches e and the spring (I will bring the arms 0 into their open position indicated by the mixed lines in Figure l. Now the keys may be put on. V

The'watch is provided either with a luminous dial or a luminous bottom lined with a phosphorescent matter so that when the watch is brought near a look as shown in the c Figure 3 a beam of light will light up the key {{mle and facilitate the introducing of the The ring shown here in two pieces could also be in one piece. The parts held in the lug 6 would be one straight piece held swingingly and perpendicularly to the plane of the watch dial. The locking could be made like that in Figure 1 and the hooks would be arranged so as to work in planes perpendicular to the plane of the dial.

In the working form of the figures 4 to 7 there is only one arm 0 shaped like a stirrup and hinged with one leg to the watch-case a by means of a hinge o the axis of which is tangential to the bezel. The other leg is held "so by a clasp 19 mounted on a lug p by means of an axle pin 19 A spring p is wound around said pin and is resting with one leg on the clasp p and with the other on the arm 0. I H

The clasp is opened by pressing as indis5 cated in Fig. 6 by the arrow on one wing of the clasp. Then the clasp will be disengaged from its hold on the arm 0 and this arm will be pushed by spring p into the position V shown in Figure 6. ea

In the working form of the Figure 8 the arm 0 is oval-shaped and is surrounding the watch. It is open on one long side. With its other side it is hinged to the watch-case a. The ends of the open side of the oval are caught ina clasp p which is of a similar arrangement as that shown in the Figures 4 to 7.

What I claim as new is:

1. The combination of a key ring anda d lighting device for the same, comprising a key ring made in two halves, a Watch case having a. luminous surface arranged inside of said ring, a pendant with a flanged part, a lug on the opposite side of the bezel as support or the hinges at the ends of the halves of the ring two tailed hooks pivoted on the flanged part of the ()BDClLUlt, a helical spring on the stem and inserted between the tail ends of the hooks and the bezel and adapted to press the said tail ends against the bottom of the pendant, a pusher knob carrying two pins mounted slidingly in the pendant and a Washer inserted on the underside of the pendant between said pins and the tail ends of said hooks, notches provided at the free ends of the two halves of the ring, said notches engaged by said hooks forming the locking means of the ring, and a leaf spring held in said lug and bearing with its ends on the hinged ends of the ring and adapted to open the latter when the knob is pressed down.

2. The combination of a key ring and a lighting device for the same. said combination comprising a Watch having a luminous surface, a ring concentric to said Watch, means for attaching said ring to the bezel in spaced relation to the Watch case, said means consisting of a hinged part and a detachable partfor said ring.

In testimony whereof I afiix my signature.
